For plastic pails in terms of application, the surface of plastic pails must not have traces, especially whitish and black spots.
In order to ensure the surface quality of the product, the plastic pail manufacturer needs to pay great attention to the machine, especially the high temperature required for the production, the injection pressure, the injection speed and other process parameters to fine-tune so that the mold is not satisfied when injecting the plastic and that there is no internal stress leading to deformation and cracking of the product.
The effect on the shortening rate of plastic drums depends mainly on the plastic structure. For example, the shrinkage rate of thick-walled plastic parts is greater than that of thin-walled plastic parts; the shrinkage rate of plastic products with lined uppers is less than that of unlined uppers. The shortening rate of plastic parts with messy shapes is less than that of simple shapes. The height direction of plastic parts is usually smaller than the horizontal direction. The length of slender plastic parts is small; the reference in the length direction of the plastic part is smaller than the reference in the thickness direction. The shortening rate of the bore is large, and the shortening rate of the shape is small. In addition, the plastic barrel must have a certain strength and wear resistance, and be able to resist impact, heat-resistant parts, chemical resistance and water absorption.
The above is about the plastic barrel in the production and processing will affect the late molding of several aspects, I hope the above content will have some help to you, more information related to the editor will be successively collated and released to the website, thank you for watching.
